Here are some quotes of C.S. Lewis that I found here.
If the whole universe has no meaning, we should never have found out that it has no meaning: just as, if there were no light in the universe and therefore no creatures with eyes, we should never know it was dark. Dark would be without meaning.
Mere Christianity (New York: McMillan, 1952), p. 46.
“I am trying to prevent anyone saying the really foolish thing that people often say about Him: “I’m ready to accept Jesus as a great moral teacher, but I don’t accept His claim to be God.” That is the one thing we must not say. A man who was merely a man and said the sort of things Jesus said would not be a great moral teacher. He would either be a lunatic on a level with the man who says he is a poached egg or else he would be the Devil of Hell. You must make your choice. Either this man was, and is, the Son of God; or else a madman or something worse. You can shut Him up for a fool, you can spit at Him and kill him as a demon; or you can fall at His feet and call Him Lord and God. But let us not come with any patronizing nonsense about His being a great human teacher. He has not left that open to us. He did not intend to.”
Mere Christianity (New York: McMillan, 1952), pp. 55-56.
It cost God nothing, so far as we know, to create nice things: but to convert rebellious wills cost Him crucifixion.
Mere Christianity (New York: McMillan, 1952), p. 179.
Thus strict materialism refutes itself for the reason given long ago by Professor Haldane: “If my mental processes are determined wholly by the motions of atoms in my brain, I have no reason to believe my beliefs are true…and hence I have no reason for supposing my brain to be composed of atoms. “
(Possible Worlds, p. 209)
“Who is Aslan?” asked Susan.
“Aslan?” said Mr. Beaver. Why don’t you know? He’s the King. He’s the Lord of the whole wood…
“Is he a man?” asked Lucy.
“Aslan a man!” said Mr. Beaver sternly. “Certainly not. I tell you he is the King of the wood and the son of the great Emperor-Beyond-the-Sea. Don’t you know who is the King of Beasts? Aslan is a lion-the Lion, the great Lion.”…
“Then he isn’t safe?” said Lucy.
“Safe?” said Mr. Beaver. “Don’t you hear what Mrs. Beaver tells you? Who said anything about safe? ‘Course he isn’t safe. But he’s good. He’s the King, I tell you.
